My.conf setting for suiteCRM 7.12 Version for page load performance

Hello Team,
Recently I upgraded my suitecrm version from 7.10 to 7.12 from ubuntu 18 lts to Centos7

I am facing a page load issue, it took more time, do you have any idea what is the issue,

my system config is
32 core vcpu with 32 GB ram, with raid 5 config.

Server version: Apache/2.4.6 (CentOS)
PHP 8.0.29
mysql server version: 5.7.43

Below are the settings we have kept on my. conf file for performance optimization.

key_buffer_size = 100M
max_allowed_packet = 256M
thread_stack = 192K
thread_cache_size = 25
max_connections = 350
table_open_cache = 300
sort_buffer_size = 4M
join_buffer_size = 4M
read_buffer_size = 256


Please suggest, hope the given config is okay for the above configuration.
